To all whom 'it 'may concern:

Be it known that I, WILLIAM C. Hime-- NER a citizen of the United States, residing at Buii'alo, in the county of Erie'and State of New York, have invented a new and useful Improvement in Photogra hic-Printing Apparatus, of which the fo lowing is a specification.

This invention relates to the production of several photogra hic prints upon the same sensitized sur ace in predetermined positions.

A plurality of printing surfaces formed upon the same sirable in a variety of cases. For instance, when a large edition is to be printed plurality of printing surfaces uonmthe samel stone orvp ate would permit t e production of a corresponding number, of impressions simultaneously an would correspondingly increase the output and shorten the time required for printing the edition. Or, when several multi-colored Victures or representa'- tions are to be prin uponthe same sheet, for instance, in a newspaper, the employment of a corresponding number of printin surfaces ony the .same plate or stone woul produce in a single impression all of the pictures or representations on the sheet in the same color. In all of these and similar casesit is however essential to success that the several printing surfaces on 'the plates or stones for the dlii'erent colors should be in exact register, and the object of this invention is to produce a photographic printing apparatus'by which a plurality of printin surfaces can be produced u on a sensitlzed surface in predetermine locations with great certainty and accuracy .and in a` very expeditious and inexl ensive manner.

The a paratus comprises, riefly stated, a holder Enr the sensitized plate or stone, a hood or housing which contains theilluminatin apparatus and the transparent printing p ate, negative or ositive and which is movable over the'sensitized plate or stone so that it can be adjusted to stand opposite any desired portion thereoffu on which aphotograph print is to be ma e, and scales or graduations by means of which the adnsted position of the printin hood or ousing can be readily ascertaine and regulhted with certainly and exactn'ess, s

In the accompanying drawings, consist-ing of three sheets: Figure 1 is afront elevation late or stone would be de-l Ion an enlarged scale.

of this improved printing apparatus. Fi 2 is a fragmentary end elevation thereo Fig. 3 is a vertical section in line 33, Fig. 1. Fig. 4 is a fragmentary front view of one corner of the sensitized plate and its fastenln devices. Fi 5 is a horizontal section 1n line 5 5, ig. 4. Fig. 6 is a sectional elevation in the same plane as Fig. 3, on an enlarged scale, of the upper rtion of the frame and adjacent parts. `ig. 7 is a to plan view of the same parts. Fig. 8 is a ace view of the inner end of the printing hood, on an enlar ed scale. Fig. 9 1s a horizontal sectionin ine 9 9, Fig. 8, Fig. 10 is a vertical secion in line 10--10, Fig. 8, on an enlarged sca e.

Like letters and numerals of reference refer to like parts in the several gures.

-The statlonary frame of the apparatus .may be ojlfV any suitable construction and comprises" as shown, an upright frontframc A and si e framesl B B to which the frontframe is secured. `The front frame A consists of upright side pieces 20, a transverse top bar 21 and a lower transverse'bar 22. Each side frame B com rises front uprights 23, arranged in rear o the uprights 20 of the front frame, longitudinal top pieces 24 extending forwardly therefrom to the uprights 2O of the front frame, lower longitudinal ieces 25Yextending forwardly from the uprights 23 to the uprights 20, lon itudinal bars 26, uprights 27, and longitu inal base ieces 28. The side frames are connected y transverse stays consisting of Ytubes 29 and rods 30 passing through the same.

C represents the holder for the sensitized plate or stone D mcvably mounted in the stationary frame so that it can be laced in the proper position for applying t e sensitizing material and otherwise treating the plate or stone, or in the proper ostionl for exposing it to the action of t e movable prlntin device. As shown, this holder is attache at its lower end to the stationary frame by a horizontal transverse pivot 31 and is swung on the same by means of a gear segment 32, secured to the rear side of the holder, and a worm 33 meshing therewith and journaled in the stationary frame. This worm is conveniently operated by a horizontal shaft 34 provided at one end with a hand crank and geared with the 11D shaft of the Worm by bevel gears 35. The' holder is placed in a horizontal os'ition for applying the 'sensitizing materia and in an upright position for exposing the sensitized surface. When the lio der has reached the upright position it bears against sto s' 36 on the top pieces 24 of the si e frames and is preferab y held by catches 37. The sensitized plate or stone is secured to the holder b any suitable means, for instance, as sli'own, by strips 39 fastened to the holder b screws 38 and bearing against the marginal ortions of the plate. The holder is provi ed with various sets of screw-threaded openings for adjusting the holding strips to 1p ates or stones of various sizes.

represents the rinting hood which contains an electric uminating apparatus 40 of any suitable kind and at its inner end a glass plate 4:1 to which the. negative or other transparent rinting plate 42 is attached. This hoodp is attached to a frame F which is movable u and down in a vertical carriage G, which latter is movable transversely between horizontal guides 43 on the upper and lower transverse bars 21 and 22 of the front frame A. By adjusting the hood frame u or down in the carriage and by adjusting .the latter transversely in the statioiia frame the hood ca n be adjusted to stan y op osite any desired portion of the sensitize surface. The carriage is preferably adjusted h means of a transverse screw 4A journals in the front fra'me. The hood frame is preferably ad'usted byY two upright screws 45 journa ed in the carriage and working in nuts 46 on the sides of the hood frame. The two screws 45 are simultaneously actuated by a horizontal shaft 47 geared with the screws by bevel wheels 48. Suitable scales .or aduations are rovided by means of which ie carria an the hood frame can be accurately justed. For instance, as shown, the to bar 21 of the front frame A can be provi ed with a scale 50 on which the position of the carriage is indicated by a pointer'l provided with 51, and the carriage can be a scale 52 on which the position of the hood frame is indicated by a ointer 53.

The hood E and its ame or carrier F may be of any suitable construction. shown, the hood comprises an outer rigid portion 60` in lwhich the illuminating apparat Y 40 is ar and an inner exportion 61 w ich carries at its inner end glass plate 41`. The d rtioii 60 ofithe hood is secured to t e movable frame F, while the inner extensible portion 61 is movable toward and from the holder C and the sensitized plate or stone thereon, so that the negative can be pressed closely [against the sensitized surface. For that purpose, the hood is rovided on both sides with longitudinal guide rods' 62' which are slidabl arranged in sockets'63 on the hood frame and secured at their inner ends to the frame 64 at the inner end of the extensible portion 61, and at their outer ends to a cross head 65 connected to an adjusting screw 66 which works in the outer portion of the hood frame.

The glass plate 41 is seated in the frame 64 at the 'inner end of the extensible portion of the hood and is secured therein, as represented in Figs. 8, 9 and 10, by cross bars 70 and set screws 71. The cross bars are beveled on their sides and bear against the adjacent beveled edges of the negative or printing plate 42 thereby securing the latter to t e glass plate in such a position that the face or inner surface of the printin plate projects inwardly beyond these ho ding bars and can be closely pressed against the sensitized surface.

If it is desired to provide the sensitized 'surface with a plurality of like printing surfaces, this is readily done by shifting the hood from place to place over said surface and noting the exact position of the hood in each place by reference tothe two scales. Then, upon removing theplate or stone which has been so exposed and applying the sensitized late or stonefor the next color to the hol er, the hood can be again placed into each of the former positions by4 reference to the scales, andthe prints for the second color can be made upon the second sensitized surface in exactly the same positions in which they were made upon the first sensitized surface so that they will accurately registenwith those' previously made on the plate or stone for the first color. Each additional plate or stone is treated in the same way and the resulting set of plates or stones contains on each plate or stone a plurality of printin surfaces for one color, with the correspon surfaces on the several plates or stones, in exactly the same relative position so that they will register correctly. If it is desired to provide the sensitized late with a lurality of rinting surfaces w ich diifer rom each ot er the operation is carried onl in the ,same way but different negatives are inserted into the hood for producing the different prints, as may be necessary.A Although the prints on the same plate or stone are dirent in this case, ythe corresponding prints on the sev eral stones or p ates are alike and in correct register.

The sensitized late may ber/a negative upon'which a num r of made as described, but by using ong or more transparent positives in the hood instead of one or m'ore n atives.
